2.) Steam enters a turbine at 1380 kPa with internal energy of 2705 kJ/kg and specific volume of 0.1655 m'/kg. Exhaust is at 7 kPa with internal energy 2150 kJ/kg and specific volume of 18.36 m/kg. The heat loss from the turbine is 25 kJ/kg. Determine (a) the work per kJ/kg and (b) the steam flow rate in kg/hr if the turbine produces 150 kW.
Oxygen (molar mass 32 k g / k m o l ) expands reversibly in a cylinder behind a piston at a constant pressure of 3.157 bar. The volume initially is 0.0111 m3 and finally is 0.0321 m3; the initial temperature is 17 0C. Calculate the work input during the expansion with the correct unit. Assume oxygen to be a perfect gas and take the specific heat at constant pressure as = 0 . 9 1 7 k J / k g K.
Air (MW=29 g/mol) at 115.00 kPa and 285.00 is compressed steadily to 600.0 kPa. The mass flow rate of the air is 2.00 kg/s and a heat loss of 32.1 kW occurs during the process. You may assume that changes in kinetic and potential energy are negligible, the temperature of the surroundings is 25 ∘C, and that the CP of air is 3.5 R. Given the compressor operates with a second law (reversible) efficiency of 0.60,calculate the following. What is the actual work interaction term in kW? What is the actual exit temperature of the air in Celcius?
1. Steam at a pressure of 2MPA and temperature 300°C is passed at a constant rate into a desuperheater unit. The desuperheater is accomplished by continuously spraying water at 95 °C onto incoming superheated steam. The amount of water injected is so regulated that both the water and superheated steam finally change into dry steam at 2 MPa. If the resulting mixture of dry saturated steam leaves the desuperheater at 2MPA and the rate of I kg/s, find the mass of superheated steam used per hour and the mass of water to be injected per hour. Fond also the diameter of the pipe through which the superheated steam flows to the superheater if the speed of the steam through the pipe is not to exceed 25m/s..
